Car Rental in Honolulu

Hi guys,

Is it necessary to rent a car in Honolulu? I will live in Waikiki area and will stay in Honolulu only for 7 days during Christmas.
Public transportation or order trip is good enough?

Thanks for your advise,

可以不租车，但是有车还是更方便，除非一直呆在在waikiki ---发自Huaren 官方 iOS APP

租车环岛跑一圈很有意思啊。为了自由，还是租一个好。
